    López Larraz, Eduardo; Trincado Alonso, Fernando; Rajasekaran, Vijaykumar; Pérez Nombela, Soraya; Ama, Antonio J. del; Aranda López, Juan; Minguez, Javier; Gil Agudo, Angel; Montesano Del Campo, Luis (2016-08-03)
    Article
    Accés obert
    The closed-loop control of rehabilitative technologies by neural commands has shown a great potential to improve motor recovery in patients suffering from paralysis. Brain–machine interfaces (BMI) can be used as a natural ...
  • Improving the performance of input interfaces through scaling and human motor models 

    Muñoz Morgado, Luis Miguel; Casals Gelpi, Alicia (2016)
    Article
    Accés obert
    The performance of interfaces is affected by human factors, which vary from one person to another, and by the inherent characteristics of the various devices involved. A set of techniques has been studied in order to ...
